ADSORPTION AND BINDING OF SMALL GASEOUS MOLECULES ON ONE-DIMENSIONAL PLATINUM-INDUCED NANOWIRES ON GERMANIUM(001)

Abstract

Recently developed one-dimensional Pt-induced nanowires on Ge(001) (NWs/Ge(001)) are composed of atomically dimerized arrays extending to several hundred nanometers, which provides an ideal platform for investigating the variety of physical and chemical processes. So far, a confirmed structure has not been established, hindering deeper understanding of NWs/Ge(001). In this thesis, we resolved the structure and the electronic properties of the NWs/Ge(001) surface by studying the adsorption behaviors of CO, O2, and H(g) with scanning tunneling microscopy and density functional theory calculations. Such knowledge provides better understanding of gas-solid interfacial reactions and illuminates broad perspectives of the NWs/Ge(001) surface.
